ABSTRACT:
An extendible trailer system (10) which is adapted to be coupled to the cab of a vehicle and is reversibly extendible in both the longitudinal direction (14) as well as the transverse direction (16). The extendible trailer system (10) includes a first trailer frame (18) having an extended length in longitudinal direction (14). System (10) further includes a second trailer frame (18) which is extended in longitudinal direction (14). Releasable coupling mechanism (36) allows coupling of second trailer frame (20) to the first trailer frame (18) and allows for the second trailer frame (20) to be at least partially and slidably inserted into coupling relation with the first trailer frame (18). A transverse extension mechanism (84) is provided on both the first trailer frame (18) and the second trailer frame (20) to allow for a reversible extension and retraction of the overall width of extendible trailer system (10) in transverse direction (16).
